PATIKIL 125ml Separating Funnel – Borosilicate Glass, PTFE Stopcock

Description

Product Overview

The PATIKIL 125ml separating funnel is engineered for laboratory professionals who demand precision, durability, and chemical resistance in a compact format. Constructed from high‑quality transparent borosilicate glass, the funnel offers exceptional clarity that allows users to monitor phase boundaries and liquid levels with confidence. The heavy‑wall design adds structural strength, reducing the risk of breakage under repeated use and providing a stable base during vigorous mixing or inversion.

A PTFE (polytetrafluoroethylene) stopcock at the bottom ensures leak‑free operation and smooth control of liquid flow, even when handling aggressive solvents or corrosive reagents. The conical shape promotes efficient phase separation, while the 24/29 joint size matches standard laboratory glassware, enabling seamless integration with condensers, receivers, and other accessories. This funnel is ideal for titration, liquid‑liquid extraction, and any procedure that requires reliable separation of immiscible liquids.

Beyond its core construction, the funnel includes a precision‑machined ground glass joint that guarantees a tight seal, preventing vapor loss and maintaining system pressure. The transparent body also facilitates quick visual checks for color changes, precipitate formation, or emulsion stability, helping scientists make real‑time adjustments without interrupting the workflow. Designed for both routine and specialized applications, the PATIKIL funnel balances ease of use with professional‑grade performance.

Usage

Designed for a wide range of scientific environments, the PATIKIL 125ml separating funnel excels in chemical research labs, petrochemical analysis stations, educational institutions, and quality‑control facilities. Its compact 125 ml capacity makes it perfect for small‑scale experiments, routine titrations, and sample preparation where space is at a premium. The transparent borosilicate glass allows technicians to observe the interface between aqueous and organic phases, facilitating accurate timing of the stopcock opening to collect the desired layer.

The PTFE stopcock’s low‑friction seal provides precise control, reducing the chance of accidental over‑drainage. Because the funnel is heavy‑walled, it can withstand temperature fluctuations and mechanical shocks, making it suitable for both ambient‑temperature extractions and heated processes up to the glass’s tolerance. Users can easily clean the funnel by rinsing with appropriate solvents, and the PTFE components resist chemical attack, extending the product’s service life.

In addition to standard laboratory use, the funnel proves valuable in field‑based analytical work where portability and robustness are essential. Its resistance to acids, bases, and organic solvents means it can be employed in environmental sampling, pharmaceutical formulation, and even forensic investigations. The 24/29 joint compatibility ensures that the funnel can be paired with a variety of adapters, allowing custom setups for specialized protocols such as azeotropic distillation or multi‑stage extractions.
